Therefore, a more lengthy description is regarded as unnecessery.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

What is claimed is:-

1. A seat mounting and connecting device for use in association with agricultural machinery comprising a substantially solid body of compressible, yieldable and shock insulating properties having horizontal passages extending transversely therethrough adjacent its upper and lower ends, tubular metal bushings fitted in said passages to serve as reinforcing, connecting and wear members, substantially duplicate metal cups capped over the opposite ends of said body, attaching and assembling bolts passing through said bushing and separably connecting with the rim portions of said cups and detachably connecting the rim portions to the adjacent ends of said body, means on the lower cup for operative connection with the frame of the machinery, the upper cup being provided with an integral upstanding shank terminating in a ball joint connector, and an adapter bracket comprising an attaching plate and a sectional socket adjustably fastened to said ball joint connector.

2. As a component part of a seat connecting device of the class described, a substantially circular cup adapted to fit in a cap-like manner over one end of a complemental cylindrical block of rubber, said cup including a disk portion formed with a centrally located laterally projecting shank terminating in an integral ball connecting head, and a companion adapter and attaching bracket comprising a pair of identical complemental flat plate sections separably contacting each other and bolted together, said sections being formed at corresponding ends with portions defining a spherical socket adjustably and detachably clamped to said ball connecting head, and being formed at their opposite ends with right angularly disposed duplicate outstanding flanges disposed in a plane flush with each other and in parallelism above the disk portion of said cap and providing a unitary attaching member suitable for connection with a conventional operators seat, the rim portion of said cup being provided with diametrically pposite bolt holes, and a bolt and nut cooperable with said rim and holes.

3. A seat mounting and connecting device for use in association with agricultural machinery comprising a vertically elongated solid rubber body cylindrical in cross-sectional form, said body having fiat ends and being provided adjacent said ends with centrally arranged horizontally disposed metal lined passages, a circular metal cap fitting over the lower end of said body and provided with integral means for operatively connecting it to a conventional supporting arm or the like, a second substantially duplicate circular metal cap fitting telescopically over the upper end of said body and provided with means for attachment to a conventional operators seat, and bolts passing through metal lined passages and connected with the rim portions of the respective caps to hold the caps removably and adjustably in place.
